20120312210 | CULTIVATION AIR SEEDER WITH VISUALLY ENHANCED SEED HOPPER - A cultivation air seeder has an ornamental facing around three sides of its large, metallic bulk seed hopper to enhance the appearance of the hopper and provide environmental protection for sensitive mechanical, electronic and hydraulic components. A front section of one facing panel on each side of the machine is hinged about a generally upright axis to allow the panel section to be opened and closed like a door for operator access to the components behind it. The facing can be stylishly molded from a synthetic resinous material or other non-metallic substance to facilitate manufacture and is disposed to conceal unsightly weld lines and other imperfections on the exterior surface of the hopper. | 12-13-2012 |
20120312211 | SEED DISTRIBUTION TOWER FOR AN AIR SEEDER - The seed distribution tower of an air seeder splits a single, primary stream of conveying air and seeds into a plurality of secondary streams for delivery to openers that deposit the seeds into the ground as the seeder advances. As seeds enter the head of the tower in an upward vertical direction through an inlet at the bottom of the head, they are scattered 360° in a horizontal direction by an inverted, overhead distribution cone. The inlet through which the seeds enter the distribution head has an eased configuration to reduce turbulence and promote laminar flow within the head during the dramatic transition from vertical to horizontal movement. Sensitive components such as tram line valves, solenoid actuators, and blockage sensors are protectively housed within the interior of the distribution head to avoid exposure to hostile environmental elements. | 12-13-2012 |
20120316673 | AGRICULTURAL IMPLEMENT HAVING HOPPER WEIGHING SYSTEM - An agricultural seeding implement has a seed hopper that is weighed continuously during field operations as the seed volume in the hopper progressively diminishes. The weight information is used to perform ongoing control functions on the implement. One embodiment uses the weight information to reduce the down pressure on compaction wheels of a wing section of the machine as a function of the diminishing weight of the hopper on the main section. | 12-13-2012 |
20120316736 | CULTIVATION AIR SEEDER HAVING SEQUENTIALLY OPERATED TOOLS - When the operator of a cultivation air seeder shifts the tractor valve to raise the cultivators and openers from the ground as the seeder prepares to turn around at the end of a field, the operating and control system of the seeder causes the cultivators to be raised first, followed in sequence by the trailing openers. The seed meter turns off as soon as the cultivators leave their lowered position, but the blower stays on so that seeds in the conduits downstream from the meter continue to be delivered to and deposited into the ground by the openers until the cultivators reach their raised position, whereupon the openers are raised. Depending upon the particular seeding mode selected by the operator, the cultivators and openers either lower simultaneously as the operator shifts the tractor valve to the lowering position when starting down the next pass, or the cultivators are lowered first, followed in sequence by the openers. Regardless of the selected seeding mode, the seed meter turns on as soon as the cultivators reach their lowered positions. | 12-13-2012 |
